Assertion : The refractive index of diamond is square root of 6 and that of liquid is square root of 3
If the light travels from diamond to the liquid, it will totally reflected when the angle of incidence is 30o
Reason :mu equals fraction numerator 1 over denominator sin invisible function application C end fraction where mu is the refractive index of diamond with respect to liquid
